Children from low income families generally suffer from hard conditions,such as poor living conditions, inadequate nutrition, and delay in accessing health care services. Such problems may made children suffer from developmental problems and malnutrition and to have a lower level of intelligence and difficulties in language comprehension, which may not only have profound impacts on children's physical well-being, but on their psychological well-being as well. Musical training is considered to have potential for promoting psychological well-being among children mostly because music is found to be important to a child's early psychological development. A growing number of educators and researchers suggest that, of all the stages of life, infancy may be the time when music has the most important impact on an individual. Babies hear language long before they are able to comprehend it. The quality and the quantity of what is unconsciously absorbed in infancy relates directly to later development. Musical training has been used for various purposes such as improving language development, self expression, memory skills, concentration, social interaction, fine motor skills, listening, problem solving, teamwork, goal setting, and coordination. More importantly, when a child learns to sing and play music, other areas of development — creativity, family bonding, self-esteem, confidence, emotional development — are also positively impacted.
